I took the silent thunder off of my 271 last year. It sounds much better, no more rumbling and rattling noise. I used the tips that were already installed and just added some rubber flappers on the outside. As far as performance, I didn't really see any change.

Its off and I like it
Removed my Silent Thunder box Sunday. 4 bolts two guys and it fell right off. The tips are fine just need external flaps. No sound ordinance here. The weight of that box is equal to a grown man. I am going to like having it off.

Silent Thunder Exhaust
I have a 1988 Formula SR-1 22.3 LS and I would like to buy an Exhaust box. The box I have now is broken at the eye loop and I don't know how to repair it? If any one can help.

pull the box, add flappers, and make some noise. '02 353, 500EFIs, Corsa when I need it. I'm the only powerboat in a private marina of blowboaters. I take great joy in heading to the marina on Wednesday's (Regatta day) and firin' 'em up and providing a nice bass note rumble to their festivities
